With all of his family cultivating in his Artifact, Yang Rai could keep track of everyone's growth at every step of the way. He did this while working on the secret he is keeping. Lan You Ruo was the only one who could see the progress. So they had a conversation at the construction location. One of the few times that he even let her near it. It was lucky for her since she had to be involved in the project monitoring.
"This… is… Massive. How did you even get this much done? With it this far along it could be ready in a year."
"You forget Lan You Ruo. This is just the home base. I can't just send my people to a battlefield without proper equipment. There is also a lot more work to be done."
"It looks almost done."
"Not quite yet. I'll have everything finished within the allotted time frame. But there are a lot of other things that need to be done."
"Well I won't stay and keep you from this. I should tell you though there are 800 new women. This endurance of yours is quite something husband."
That was the last thing she said before she left to continue her cultivation. Yang Rai would continue his work.
After 150 years inside there was enough materials to create another Highest rank tree and Yang Rai did exactly that. For each new synergy generator he would be able to synthesize more of them faster. He made sure to do this at the exact moment there was enough. He could tell he was going to need a ton of these resources.
When he took some time away from the construction to have his soul clones practice he took out the good thing he found on Shining Star World. It was a very special kind of grape vine. The alchemic Grape wine, It grew grapes that had similar properties to Open Heaven pills. The best part is that in his hands it would make the best possible Open Heaven Grapes possible. Thus they had no impurities. It was a very good thing. He made a ton of these vines and had the world spirits use it for brewing.
Over the next 500 years his wives count jumped up to well over 2000 women. They still didn't seem satisfied with that number. While that happened they all rapidly began forming their Dao seals. Some were new ones he didn't have before and thus received one as well. This brought him so much joy and sorrow at the same time. Knowing that with each new seal he is going to need to make a ton of glyphs to occupy each one and refine so many spirits into his own being.
By the end of the 1000 years all of his wives had at least condensed their Dao Seals. Most were now all straight promote 8th ranks or better. And many of them that had previously ascended to the Open Heaven Realm comprehended at least 1 Divine ability Manifestation. It was truly a massive amount of improvement.
As for Yang Rai, he increased his Highest rank generators again. As well as his glyphs strength up to T14 R4. Along with now perfect control of his soul clones. He was powerful.
